I believe they usually do something like:

foreach( num, ref elem; liaOrig){

}

which creates the index num and the reference to the element of 
range liaOrig.

It also seems that a lot of discussion is going on about reducing 
use of foreach loops in their preferred style, so you might want 
to try some of that.
